STEAM-ENGINE.

To all whom t may concern.'

Be it known that I, GEORGE E. QUIGLEY, a citizen of the United States,and a resident of Youngstown, in the county of Mahoning and State ofChio, have invented certain new and useful Improvements in Steam-Engines, of which the following is a specification.

My invention relates to steam engines, and it consists in thecombinations, constructions, and. arrangements herein described andclaimed.

An object of my invention is to provide a steam engine having a cylinderbody which does not have to be cored, owing to the fact thatpassage-ways or ports are provided in separate port carriers.

A further object of my invention is to provide an engine in which thecoring of the cylinder saddle is obviated.

A further object of my invention is 'to provide an engine having a novelform of bushing in which the slotting of the bushing is eliminated, thesaid bushing being held in position by novel holding devices.

A further vobject of my invention is to provide an engine having acylinder yand a valve casing, said cylinder being provided with portcarriers for establishing communication between the cylinder' and thevalve casing, the said port carriers also serving as means forsupporting the valve casing. y

A further object of my invention is to provide an engine having meansfor carrying ofi' the exhaust steam, which is not dependent upon a coredsaddle, but which may be used with any suitable form of cylindersupport.

Other objects and advantages will appear in the following specification,and the novel features of the invention will be particularly pointed outin the appended claims.l

' My invention'is fully described in the following specification, yofwhich the accompanying drawings form a part, in which the same referencecharacters are used to designate the saine parts in each of the views,and in which r- Figure l is a central, longitudinal, vertical, sectiontaken through one unit of alocomotive engine constructed in accordancewith my present invention, Fig. 2 is a section taken on the line 2-2 ofFig. l; Fig. 3 is a section taken on the line 3?) of Fig. l; Fig. l is aplan view of twoconnected units; Fig. 5 is a perspective view of one rofthe Specification of Letters Patent.

cylinder heads which I employ; Fig. 6 is a section taken on the line 6-6of Fig. 4.

ln the drawings forming a part of this application l have shown apresent preferred form of embodiment of my invention as applied to alocomotive engine, comprising cylinder body ct, having exactly similarheads l), two exactly similar port casings or carriers c, interposedbetween the cylinder body and corresponding heads, two exactly similarvalve chamber casings (Z joined together between the port carriers, twoexactly similar valve Vchamber extensions e on the outer' faces Yofcorresponding port carriers, two exactly similar bushings within thevalve chamber, and two exactly similar exhaust Ts /L connected withcorresponding valve chamber extensions e of each ofthe units of theengine, as shown in Fig. 4, and a T c' exactly like the Ts it andjoining the same.

The valve chamber casings CZ are joined together by means of bolts Z2and to the corresponding port carriers c by means of bolts cZS, and eachof said casings having an inlet connection (Z4, one for the steam andthe other for the relief valve, and 'said port carriers are connectedwith the cylinder a by means of bolts a2, said cylinder being shown witha bushing or lining a3.

The` cylinder heads are connected with the corresponding port carriers oby means of bolts b2, each of said' heads having an inwardly directedmember b3, extending into the .opening c2 of the corresponding portcarrier, internal webs o4, an external boss b5 and screw -threadedopenings 226 therethrough, each of which is adapted to receive a glando7 or bs, the former of which is bored for the piston rod e of thepiston y7a2, and the latter being blind for the closed end of thecylinder, and it willbe seen that said heads Z) are readilyinterchangeable.

The valve chamber extensions e are connected with corresponding portcarriers by means of bolts e? and have, each, a head e3, exactly alike,connected therewith by means of bolts c4, each of said heads having aboss e5 thereon provided with a screw-threaded opening therethroughadapted to receive eitherof two glands e7 or es, the former of which isbored for the stem Z of a double valve Z2, and the latter of which isblind at the closed end of thevalve chamber, and

c the exhaust Ts I1, vare connected with correspending valve chamberextensions e by Vholding the bushing.

ing c3 communicating with the interior of the cylinder a., and tivoopenings c* and c5 1n register and communicatmg` with the correspondingvalve chamber casings Z and extensions e, the bushings resting Withinthe openings c4 and c5 or" the corresponding port carriers, and itWillbe noted that the said bushings are each providedwith a plurality ofports f2 communicating with the interior of the corresponding portvcarriers whereby dead 7 steam may be exhausted from the cylinder to theT i, at each end of Vsaid cylinder, alternately, this being controlledby the members Z3 01"' the valve Z2, said members also controlling theadmission of steam to the cylinder, on opposite sides of the piston 76,2from the inlet d4, through corresponding port carriers.

In assembling the engine, the body portion 'a of the cylinder isprovided With a bushing a3 as stated, Which is simply a cylindricalmember Without any cut-away portion or opening. rlhe bushing is held inplace by means of the Webs b4 on the cylinder heads Z). These Webs, asvvill be seen from the drawings, project through the opening c3 in theport carrier c. This means of holding the bushing in place, does awayWith any necessity of theuse ofdowel lpins or other similar devices, andeliminates the necessity of boring dowel pin holes through the bushingor the-body of the cylinder. The provisio-n of they ports or passages inthe port carrier c eliminates'the necessity of having intricate coredpassage-Waysin the body a of the cylinders. The latter is, like thebushing, a single member Which does not require machining to provideports or means for They Dort carrier Vc serves a double purpose, for itnot only provides a passage-Wayfor the steam, but it also serves as asupporting means for the valve casing. Y f

The provision of the exhaust Ts obviates the necessity of providing aycored saddle for the cylinders. The cylinders, therefore, may besecured to any convenient portion of the engine or locomotive.

The operation is in all respects similar to that of the conventional'engines, but it will be seen that,rin the event of injury to any partthereof, such part may be quicklv and easily replaced, for the mostdelicate and most inaccessible port slots of the present type of enginesis rendered quickly and y easily Vaccessible, and replaceable, only theyparticular port` carrier being removed and another substituted therefor,and it Will also be noted that, in the event of an irreparable injury,only the port carrier is scrapped, and no tying up of the locomotive isnecessary beyond the few hours required to substitute na new portcarrier. rIhis is equally true ofy the other parts, such as the cylinderheads, the glands therein, the valve chamber casings, the extensionsthereof, the bushings therein, the heads of said chamber, and the glandsthereof, it not being necessary to take down the entire engine toreplace any of these parts, and only a small portion of the engine needbe scrapped if found irreparable, ysubstitute parts being carried instock in all shopsV along the right of Way, and, if the cylinder ashould be badly damaged, only a relativelyV small casting need bescrapped. Further, because 'of the `number of joints, the liability ofinjury to the engine A is minimized because Yof the comparativeflexibility at such points, and the original cost of production of theengine is greatly reduced because of the i'act that the cylinder andvalve chamber are absolutely distinct from each other, and comprise,each, relatively simple parts requiring little machining as comparedwith the cumbersome cylinder castings as now provided, with theintricate machining thereof.

Thile I have shown an adaptation of my invention to locomotive engines,it will be obvious that I may .adapt the same to marine and stationaryengines as Well, and I may malte structural changes Within the scope ofthe appended claims over the details illustrated in order to adapt thesame to such other uses, but I have shown the same in connection Wit-h alocomotive because of the exposure of such engines to sudden atmosphericchanges in temperature over the steam temperatures. Y
